Installing a Trail Tech Vapor

This is one of the aftermarket gauge sets that has actually been used on a couple EX250s. One of the club people says: "It's accurate and has more features than the stock gauges." And another: "I've had those gauges on my bike for a couple months now and they work great."

Here are some mounting tips, although, as with all mods, you're guaranteed to run into something you're going to have to figure out for yourself.

• Get Trail Tech part# 75-300. If you're not sure, call Trail Tech directly. This model has worked on the EX250.

• You'll have to cut the hose to the radiator to install the temp sensor.

• Run the tachometer wire to one of the coils, instead of wrapping it around a spark plug wire as the directions say.

• For the speedometer, use the magnet that is supplied, and follow the directions for attaching that magnet that are in the bicycle speedo article. Epoxy or JB Weld work to hold the magnet to the brake rotor. Run the wire for the speedometer along the brake hose.

• For power use the wiring for one of the bulbs that illuminated the stock gauges. That way the Vapor will turn on when the key is on.
